My Dear Kali, I See Nobody Payed Attention To Your Question So, If It´s Not Too Late Here It Is...
The Best Way To Reach islands Is, Of Course, By -Boat
OK, I Will Get Serious Now:
Boat Links Between Dubrovnik and The Islands (Especially The Three Biggest Islands -Kolocep, Sipan, and Lopud) Are Excellent -There Are Several Jarolinija Ferries Every Day. that Way You Can Visit Islands On The Daily Basis Or Even Make It An Excellent Overnight Stay. Moreover, There Is A Fast Passenger Boat (named The Nona Ana) That Runs Between Dubrovnik And The Islands In The Summer. There Are Also Organised Trips To The Islands, But In The Summer...
Anyway, I Hope This Helped A Little, And For More Detailed Lines Visit Jadrolinija´s Page!
